Doc: fix confusion about LEAKPROOF in syntax summaries.
The syntax summaries for CREATE FUNCTION and allied commands
made it look like LEAKPROOF is an alternative to
IMMUTABLE/STABLE/VOLATILE, when of course it is an orthogonal
option. Improve that.
Per gripe from aazamrafeeque0. Thanks to David Johnston for
suggestions.
